Product Description
- 产品描述
-
A current transformer is an instrument that converts high primary current into low secondary current based on the principle of electromagnetic induction for measurement. A current transformer is composed of a closed iron core and winding. Its primary winding has very few turns and is connected in series in the circuit where the current needs to be measured.
Therefore, it often has all the current flowing through the circuit, and the secondary winding has a relatively large number of turns. It is connected in series between the measuring instrument and the protection circuit. When the current transformer is working, its secondary circuit is always closed. Therefore, the impedance of the series coil between the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to a short circuit. A current transformer is used to measure by converting the high current on the primary side into a low current on the secondary side, and the secondary side must not be open circuited. The entry introduces its working principle, parameter description, classification, usage introduction, etc.
